The performance of any system is only as good as it's weakest link,
the aim (especially if you're the one paying the bills) is not to
remove all bottlenecks, but to equalise them so that no one
subsystem is dragging down the overall performance.
Prime targets for benchmarking MUDs must be...
- Disk space
The performance of any subsystem can usually be improved either by
throwing money at it (more memory, more/faster processors, bigger
pipe, more/faster disks), by replacing inefficient algorithms or by
some trade off against other subsystems. You can improve your
bandwidth figures by implementing MCCP, but it'll hurt your memory
and processor stats for example.
Obviously these measures mean nothing without an x-axis to chart
them against, candidates here could be:
- Concurrent connections
- Total playerbase
- No of mobs/rooms/objects
- Commands received / minute
So now we have some stats that we can actually use to compare MUDs
in an almost system independent way (processor utilisation could be
To make these useful however we now need to relate these stats to
quantities that have some real significance, i.e. cost and response
Now we're in a position to do some serious what-if modelling and get
a better bang for our buck.
IMO the first step that's needed if we truly want to be able to
compare MUD with MUD is to agree on a standard set of stats to
We need a volunteer to coordinate all the work and report on
progress (I'm way too busy unfortunately), any takers?
